The kilometer, metre, centimeter, inches and foot are the units of distance and length. While kilometer andmetre are used for long and average distances, and length, centimeter, inches and foot are used to measure short distances.
Length and Breadth
Length is longer dimension of an object while breadth is the dimension from side to side. Let's see the picture given below:
Measurement
In the above mentioned picture, the longer dimension is AB and CD. Hence AB and CD are lengths. While dimension from side to side are AC and BD and it is called breadth.
Now Remember,
kilometer =metre
metre = centimeter
andfoot =inches.
Now ifkilometer =metre
thenkilometer = Twometers.
Kilometer = Threemeters and the process goes on.
Similarly,
metre =centimeters.
metre = twocentimeters
meters = threecentimeters and the process goes on.
Againfoot =inches.
foot = twoinches
=inches.
foot = threeinches
= inches.
Remember again
Short forms:
Kilometer =
Metre =
Centimeter =
